Do any such bridges exist? I've never heard of them. io space accesses
are implemented by the host bridge, so I think the most generic we need
to support is one per host bridge, ie root bus.

the nation that is attacked, and every man will be glad of those
conscience-soothing falsities, and will diligently study them, and refuse
to examine any refutations of them; and thus he will by and by convince
himself that the war is just, and will thank God for the better sleep
he enjoys after this process of grotesque self-deception." -- Mark Twain
